Early onset on FGR in 20 weeks.

I was diagnosed with PCOD & was having irregular periods. After 3 years i conceived normally. In my 12 weeks NT scan n dual marker test everything was normal. In the 4th month i had experienced spotting several times and once bleefing was so heavy that I got admitted to the hospital and also there was leakage of amniotic fluid. After I was discharged I had an ultrasound and the doctor said that everything is normal the liquor is also normal after one month I went for an anomaly scan a quadruple marker test in which it was found that i I was having level 1 FGR also the quadruple marker test shows that I have high risk for ntd and trisomy 21. I am 20 weeks & 4 days pregnant and my baby weight is only 202 grams. Is there any possibility that my baby will regain its growth and I will have a full term baby if if the NIPT test comes out negative.
